Warm-up Friday Write down some differences between 2-dimensional and 3-dimension shapes. Name at least 3 dimensional shapes

Solid Figures M6G2: Students will further develop their understanding of solid figures E.Q. What are the basic solid figures, and what are their properties?

Plane Figures Two-dimensional Shapes (2D) These shapes are flat and have no depth. They have two dimensions – length and width.

“Solids” Three-dimensional Shapes (3D) These shapes are also called “solids” They have three dimensions – length, width and height (or depth).

Face Part of a shape that is flat For example: A cube has 6 faces

Edge The line where two faces meet. A cube has 12 of edges.

Vertex (Vertices) The place where three or more edges meet. This pyramid has 4 of these.

Cube A three-dimensional shape which has 6 square faces all the same size. Some faces parallel Some edges parallel Some faces perpendicular Some edges perpendicular

Rectangular Prism A three-dimensional shape which has 6 rectangular faces. Some faces parallel Some edges parallel Some faces perpendicular Some edges perpendicular

Cylinder A three-dimensional shape with circular ends of equal size. Some faces parallel Some edges parallel Some faces perpendicular No edges perpendicular

Cone A three dimensional shape with a circle at its base and a pointed vertex. No perpendicular faces or edges No parallel faces or edges

Square base pyramid No faces perpendicular Some edges perpendicular No faces parallel Some edges parallel

Pyramid A three-dimensional shape which has a polygon for its base and triangular faces which meet at one vertex. E.g. Triangular pyramid Square pyramid Hexagonal pyramid Pentagonal pyramid

a three- dimensional geometric shape that tapers smoothly from a flat, usually circular base to a point called the apex or vertexgeometric shape

Prism A three dimensional shape that has the same cross-section all along its length.

Three Dimension Figures Have Faces, Edges, and sometimes one or more Vertexes or Vertices

Ticket Out The Door Name as least 4 “SOLIDS” that you see in the real world.

Volume of Pyramids and Cones

Sphere A perfectly round three-dimensional shape, like a ball. It has only one curved face. No perpendicular faces or edges No parallel faces or edges

Rectangular Prism A rectangular prism is a space figure with six faces, eight vertices, and opposite sides parallel.

Hemisphere A three-dimensional shape that is half a sphere. No parallel faces or edges No perpendicular faces or edges

Perpendicular A line that is drawn in a right angle to another line. In solid shapes edges could be at a right angle to one another. Faces could also be at right angles to one another.

Parallel These type of lines stay the same distance apart for their whole length. They do not need to be straight or the same length.
